样式化 `select2` 插件

  • 772

有这样的插件select2。我想这样设计它：

在此处输入图像描述

但是这里有问题，当我用绝对定位显示选中的选项时，就input显示在外面了。

你能告诉我要走哪条路才能达到如图所示的结果吗？

$(document).ready(function(){
  $('.__select2').select2({
        placeholder: 'Select an Industry',
        allowClear: false,
        tags: true,
        maximumSelectionLength: 5
    });
});

    .select2-container--default .select2-selection--multiple .select2-selection__rendered {
    position: absolute;
    top: 100%;
    height: 0;
    overflow: visible !important;
    white-space: nowrap !important;

.select2-container--default .select2-selection--multiple .select2-selection__choice {
    float: none !important;
    display: inline-block;
    position: relative;
}

.select2-container--default .select2-selection--multiple .select2-selection__choice__remove {
